The Forgiver
وَأَنذِرْهُمْ يَوْمَ ٱلْـَٔازِفَةِ إِذِ ٱلْقُلُوبُ لَدَى ٱلْحَنَاجِرِ كَـٰظِمِينَ ۚ مَا لِلظَّـٰلِمِينَ مِنْ حَمِيمٍ وَلَا شَفِيعٍ يُطَاعُ
And warn them, [O Muhammad], of the Approaching Day, when hearts are at the throats, filled [with distress]. For the wrongdoers there will be no devoted friend and no intercessor [who is] obeyed.

يَوْمَ هُم بَـٰرِزُونَ ۖ لَا يَخْفَىٰ عَلَى ٱللَّهِ مِنْهُمْ شَىْءٌ ۚ لِّمَنِ ٱلْمُلْكُ ٱلْيَوْمَ ۖ لِلَّهِ ٱلْوَٰحِدِ ٱلْقَهَّارِ
The Day they come forth nothing concerning them will be concealed from Allah. To whom belongs [all] sovereignty this Day? To Allah, the One, the Prevailing.
ٱلْيَوْمَ تُجْزَىٰ كُلُّ نَفْسٍۭ بِمَا كَسَبَتْ ۚ لَا ظُلْمَ ٱلْيَوْمَ ۚ إِنَّ ٱللَّهَ سَرِيعُ ٱلْحِسَابِ
This Day every soul will be recompensed for what it earned. No injustice today! Indeed, Allah is swift in account.
يَعْلَمُ خَآئِنَةَ ٱلْأَعْيُنِ وَمَا تُخْفِى ٱلصُّدُورُ
He knows that which deceives the eyes and what the breasts conceal.
وَٱللَّهُ يَقْضِى بِٱلْحَقِّ ۖ وَٱلَّذِينَ يَدْعُونَ مِن دُونِهِۦ لَا يَقْضُونَ بِشَىْءٍ ۗ إِنَّ ٱللَّهَ هُوَ ٱلسَّمِيعُ ٱلْبَصِيرُ
And Allah judges with truth, while those they invoke besides Him judge not with anything. Indeed, Allah - He is the Hearing, the Seeing.
